Fuel pump Problems AGAIN

[Markd89]

Having gone through 6 fuel pumps surely something is wrong or im very very inlucky.

Tigra 1.4 16v
Corsa 1.6 16v

I have used an astra one for the last week and it runs perfect other than the very lour noise it makes so today i decided to change it to a corsa sport fuel pump.
It lasted 5 minutes and died down the street.

Would it be best getting one from a vectra / calibra 2.0

I got the astra one from a 2.0 ecotech, if it wasnt from the noise i would keep using it.

How have you got it mounted? Or is it in tank?

[swedge]

is it fused?

[Markd89]

It's intank pump and its running via a relay to ignition live, one of the pumps is perfect and has run for a while but is very loud. Although the others have failed this one hasn't

[John]

is it earthed ok?

[Markd89]

Ye direct to battery earth. The problem is that they just sieze solid I can free them off if I take it out the tank and bang it on the floor and hook it up to a battery and shock it free. I'm thinking they are to small for what I need as I haven't tried anything above a 1.4 fuel pump, the astra one us fine altho noisey which was from a 2.0

have you made sure the inlet pipe is cut to the right length to fit the nova tank, using the spi pump as a guide? people have squashed the ends before & had big trouble

and also, have you got the tank clean & is there enough fuel?

[Markd89]

Tank is full with 30ltr of fuel, I measured the pumps I used and the full unit is 8 inches and everytime I trim them I make sure its the same size as the original. It's weird that one of the pumps is fine but is just noisey, surely I can't have been very unlucky and getting knackered pumps

[peester]

why isnt it earthed to the chassis?

[Will F]

I had the same problem with my van - it was down to the fuel being contaminated - went through three pumps in two days.

[Markd89]

changed the fuel today and managed to get hold of a 2.5 v6 vectra fuel pump and it all seems to be fine now
cheers chaps
